INITED STATES LEMUEL D. MILLER, OF OOLLAMER, PENNSYLVANIA.

MEASURING-VESSEL.

SPECIFICATION forming part of Letters Patent No. 350,313, dated October 5, 1886.

Application filed May 15, 1886. Serial No. 202,245. (No model.)

To all whom it may concern:

Be it known that I, LEMUEL D. MILLER, a citizen of the United States, residing at 001- lamer, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Measuring-Vessels, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in devices for measuring liquids; and it consists in the novel construction and arrangement of devices hereinafter fully described, and particularly pointed out in the appended claims.

The annexed drawing, to which reference is made, fully illustrates my invention, in which the figure represents a vertical sectional view of my device.

Referring by letter to the accompanying drawing, A designates the vessel, consisting of the body portion a, having upper and lower screw-threads, b 0, upon which are screwed the bottom plate, d, and the top or cap plate, e. This top plate is provided with bearings f, in which is journaled a shaft, 9, provided with a pinion, h, which engages a rack-bar, 2', at the lower end of which is a plunger, j, having suitable packing, to cause the same to fit snugly the interior of the vessel. This rackbar has its vertical movement through an opening, k, in the top plate, and the same is guided by the raised central projection, Z, to the top of which is secured one end of a plate, m, while the opposite end thereof is attached to the cap. This plate supports a pivoted pawl, n, the free end 0 of which engages a notch on the front face of the rackbar, as at p,- and the notches serve as graduating-marks, which may be from one half pint to one gallon, according to the size of the vessel. A spring, 9, secured to the plate m, engages the pawl and forces it in the notches, and a handle, 1", secured to said pawls, serves to raise the same therefrom when it is desired to lower the plunger; and a hook, s, also secured to the capplate, serves to hold the pawl out of engagement with the notch ,on the rack-bar by catching the handle under its hook end. The bottom of the vessel has a central vertical opening, t, over which is arranged a valve, u, which opens upwardly; and an outlet-faucet, o, is provided, through which is screwed a hose or other pipe, as, a

through which flows the liquid from the large vessel or tank B. It will be seen that when the operator turns the handle y to the righthand side the shaft 9 revolves, thus revolving the pinion, thereby raising the rack-bar with its plunger, and at the same time drawing the liquid from the tank through the hose aforesaid at the same time the outlet-faucet is closed. After sufficient liquid is in the measuring-vessel the valve in the bottom closes, the faucet is opened, the handle is reversed, thus lowering the. plunger, thereby forcing out the liquid through .the faucet to a receptacle. At the same time the pawl is held by its handle from engagement with the face of the rack -bar until the desired quantity is drawn off, when the pawl is permitted to engage the notch representing the amount of liquid taken from the vessel, and this pawl is self-acting when the rack-bar is raised, and serves to gage the amount in the vessel.

Having described my invention, What I ,7 claim, and desire to secure by Letters Patent, 1s-

1. The measuringvessel describeijmr isting of the body portion having the upper and lower screw-threads, the bottom plate having female threads, and threaded opening provided with the valve, and the. outletfaucet secured to said bottom, the cap-plate having the centralopening and bearings, thecrankshaft provided with the pinion, the rack-bar engaging said pinion and provided with the plunger, and the spring-pawl adapted to engage the notches in said rack-bar, as shown and described.

2. In a measuring-vessel, the combination, with the vessel A; constructed as described, of the rack-bar having the graduatiugmarks, the crank-shaft, pinion, and spring-pawl, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

LEMUEL D. MILLER.
